Germanate PrAlGe2O7 is obtained from initial oxides Pr2O3, Al2O3, and GeO2 via solid-phase synthesis. The crystal structure of the investigated germanate is determined via X-ray diffraction. The luminescence spectra are been determined at room temperature. The effect temperature has on the heat capacity is determined via differential scanning calorimetry. The thermodynamic properties of the complex oxide compound are calculated using the experimental data on Cp = f(T) in the temperature range of 350‒1000 K.
